The Role of Carbohydrates in the Body:
-
Energy Production:
-
Primary Source: Carbohydrates are the body's main source of energy, particularly for the brain and muscles during exercise.

-
-
Supporting Brain Function:
-
Brain Fuel: The brain relies heavily on glucose for optimal functioning. A steady supply of carbohydrates ensures cognitive processes remain sharp and focused.
-
-
Digestive Health:
-
Fiber Benefits: Fiber, a type of complex carbohydrate, aids in digestion, prevents constipation, and supports gut health by feeding beneficial bacteria.

Excessive Intake:
-
Weight Gain: Consuming too many carbohydrates, especially refined ones, can lead to weight gain and increased risk of metabolic disorders.
-
Blood Sugar Spikes: Simple carbohydrates can cause rapid spikes and crashes in blood sugar levels, affecting energy and mood.

Energy and Performance:
-
Study Findings: Research indicates that athletes benefit from high-carbohydrate diets, enhancing endurance and performance.
-
Clinical Trials: Various trials have shown the effectiveness of carbohydrates in improving physical performance and recovery.
-
-
Weight Management:
-
Research: Studies suggest that diets rich in complex carbohydrates and fiber support weight loss and maintenance by promoting satiety and reducing calorie intake.
